Title:
ビデオ信号処理装置
Document Type and Number:
Japanese Patent JP4295829
Kind Code:
B2
Abstract:
Video signal processing apparatus provides for blanking main and auxiliary images in a multi-image display, e.g., a PIP or POP display, independently. The blanking may be part of a V-chip feature in which blanking occurs in response to auxiliary information, such as XDS data, that is included in a video signal to indicate the content of television programming. Main image blanking occurs only during active video intervals to prevent corrupting sync information. In a system that produces the main image from various types of video signals, e.g., composite video and s-video, that require separate signal processing paths, main image blanking capability is provided in one signal path only, such as the composite video path. The blanking capability is activated and the associated signal path is selected to provide main picture blanking regardless of which type of signal is providing the main picture.
